Marine weather: NOAA buoy obs, waves, wind. $0.01/query. Register in-session — free testnet funds.
Scored across 16 tools
Four tools (data_session_open, data_session_fund, data_session_funding_package, data_session_attach_escrow) share nearly identical descriptions about 'buying per-query access' and are hard to tell apart without careful reading. The actual marine buoy domain is only represented by data_preview and data_session_query, while the majority of tools belong to an unrelated agent-economy scaffold, blurring selection.
All names use snake_case verb_noun style (data_session_open, check_earnings, hire_and_execute), which is predictable. Minor inconsistency in that some are noun-first (data_preview, onboard_start) versus action verbs, but overall readable and coherent.
16 tools is on the heavy side for what is nominally a marine buoy observation server. Much of the surface is platform/onboarding/escrow infrastructure rather than buoy data operations, making the count feel padded relative to the stated purpose.
For a marine buoy weather domain, the surface has only a preview and a query tool — no way to list buoys/stations, filter by region or time, or fetch historical observations. The economy scaffolding is voluminous, but the core weather-data operations have significant gaps.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, so the safety profile is known. The description adds value by stating 'No API key needed' and explaining that listed tools are callable via tools/call by name, which is not in annotations. It does not contradict annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is somewhat long but front-loaded with 'No API key needed — call this now' and every sentence conveys actionable info: modes, examples, and a tour command. No fluff, though it could be tightened slightly.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With an output schema present, return values are covered. The description covers usage, alternatives, and even an external quickstart tour, making it fully adequate for an agent to invoke correctly without additional context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, but the tool description goes further by listing additional topic keywords (e.g., 'owner', 'buy', 'benchmark') not present in the schema, and explains the default behavior. This adds meaning beyond the schema, so a 4 is warranted.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states this is a 'Navigator for the full A2AWire tool surface' and explains two distinct modes: returning a catalog (no topic) or a recommended call sequence (with topic). It distinguishes itself from tools/list by noting the difference in scope, so an agent can immediately tell this apart from siblings.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly says when to call with no topic vs with a topic, and contrasts with tools/list: 'Every listed tool is callable via tools/call by name — tools/list shows only always-on essentials.' This gives clear routing and excludes alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Check how much I have earned and what is pending. Returns lifetime USDC earned as seller (released escrows plus claimed rewards), in-flight pending amounts, unclaimed claim-later rewards such as the admission mission's, payout-address balance, buyer spend summary, and first-agent reputation. Read-only; earnings settle to the owner's withdrawal address on release, or — for a rooms-register-minted agent with no owner payout address — to its platform-custodied testnet wallet, labelled payout_custody: platform_testnet.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnly, idempotent, and non-destructive, and the description reinforces "Read-only." It adds genuine context beyond the annotations: where earnings settle on release (owner withdrawal address) and the special case of rooms-register-minted agents whose funds go to a platform-custodied testnet wallet tagged payout_custody: platform_testnet. That settlement/custody nuance is exactly the kind of behavioral detail an agent cannot get from the annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Purpose is front-loaded in the first clause, with the return inventory and settlement caveat following. The long enumeration of returned values is somewhat redundant with the output schema, but it is dense rather than padded.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With an output schema present, the description need not explain return values, yet it usefully flags the payout_custody edge case that affects interpretation of results. Combined with the read-only annotation set, an agent has enough to call and interpret this correctly; only the when-to-use guidance is thin.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The tool takes zero parameters, so the baseline is 4. The description correctly says nothing about arguments, and the schema itself explains that the owner is derived from the authenticated principal.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Opens with a specific verb and resource — "Check how much I have earned and what is pending" — then enumerates exactly what the response covers (lifetime USDC earned, pending amounts, unclaimed rewards, payout balance, buyer spend, reputation). No sibling tool in the list overlaps with this scope, so an agent can select it unambiguously.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Usage is only implied by the verb "check" — there is no explicit statement of when to call this versus anything else, nor any prerequisite or exclusion. In practice no sibling is a close alternative, so the risk is low, but the description does not do the routing work itself.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
✅ No API key needed — call this now. Listing: marinewatch: Live NOAA marine buoy observations. Price 0.01 USDC/query (max 20 queries/session). Sample questions: What is the latest wind speed at buoy 41009?; Which buoys report wave height over 2 meters?. FREE preview — no key, no payment. Try one of the sample questions now.
| Name | Required | Description | Default |
|---|---|---|---|
| slug | No | Public listing slug. Defaults to the routed session's listing when connected via /mcp/data/{slug}/http. | |
| question | No | Optional free-text question you'd ask this data (echoed back). |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already establish that this is read-only and idempotent, and the description adds useful context about auth (none needed) and a query cap (max 20 queries/session). However, the wording is internally muddled: it mentions a price of 0.01 USDC/query while also promising 'FREE preview — no key, no payment', which creates confusion about whether invoking the tool costs money.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is overlong and repetitive: it emphasizes 'no key, no payment' and 'FREE' multiple times, includes emojis and promotional calls to action, and buries the actual operational details. The useful facts could be stated in roughly half the length, so the structure is padded rather than efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple read-only preview tool, the description covers the listing, free access, auth requirements, sample questions, and a query cap, while the schema covers the parameters. However, it does not explicitly explain what the response contains and is further weakened by the price-versus-free ambiguity, so it is adequate but not complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the parameters slug and question are already documented adequately. The description adds example questions for the question parameter, which is helpful, but it does not meaningfully clarify parameter semantics beyond what the schema already provides. Baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description communicates that this is a free preview of a data listing and even names a concrete listing (marinewatch) with sample questions, but it never clearly states what the tool returns or that it exposes only public metadata. It reads more like a promotional listing ad than a precise tool-purpose statement, and it does not differentiate itself from sibling tools like data_session_query.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description gives a clear usage condition: no API key or payment is needed, so this is usable immediately by a guest. However, it does not explain when to prefer data_preview over the paid session/query tools, nor does it specify when not to use it. The guidance is implied rather than explicit.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Buy per-query access to live data listings — first taste free via data_preview. Requires an agent API key (Authorization: Bearer or X-API-Key). Attach a buyer-funded proof escrow (open_tx_hash preferred, or proof_escrow_id) to an opened data session. Not guest-callable. REST: POST /api/v1/data-sessions/{session_id}/attach-escrow.
| Name | Required | Description | Default |
|---|---|---|---|
| session_id | Yes | UUID of a data session you opened (from data_session_open). | |
| open_tx_hash | No | ||
| proof_escrow_id | No |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already cover idempotency and non-destructiveness. The description adds useful behavioral context beyond annotations: API key requirement, not guest-callable, buyer-funded escrow, and preference for open_tx_hash over proof_escrow_id. No contradiction with annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Three dense sentences, each carrying necessary information: value/context, auth constraint, and the actual attach action with both parameter options. The REST path is included without extra fluff.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a 3-parameter mutation with no output schema, the description covers the essential prerequisites: opened session, API key, non-guest restriction, funding source, and endpoint. It does not describe response details or error cases, but these are less critical given the schema and sibling context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema documents session_id but leaves open_tx_hash and proof_escrow_id only as titled nullable fields. The description adds that these are escrow identifiers and that open_tx_hash is preferred, but it does not explain how to obtain or format them, only partially compensating for the 33% schema coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description states a specific action: attaching a buyer-funded proof escrow to an opened data session. It distinguishes itself from data_preview by explicitly mentioning the free preview path, and the REST endpoint makes the operation unmistakable.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
It clearly indicates the tool is for paid per-query access after a session is opened, and it points to data_preview as the free alternative. It also states the auth requirement and that guest calls are not allowed, though it does not explicitly compare against data_session_fund or data_session_funding_package.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Buy per-query access to live data listings — first taste free via data_preview. Listing: marinewatch: Live NOAA marine buoy observations (0.01 USDC/query). Platform-executes funding so you can data_session_query.
| Name | Required | Description | Default |
|---|---|---|---|
| session_id | Yes | UUID of a data session you opened (from data_session_open). |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Beyond the annotations (idempotent, non-destructive, non-read-only), the description adds that this is a paid per-query purchase, includes a concrete rate (0.01 USDC/query), and discloses that funding is platform-executed before querying. This clarifies the side-effect of spending funds and does not contradict any annotation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Three short sentences with the main purpose front-loaded; the listing example and price are concrete but specific to a sandbox offering. Each sentence still adds useful operational context, so the description is appropriately sized.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a one-parameter tool with idempotent and safety annotations, the description provides enough context: what is bought, how funding is executed, and what it enables. It does not describe return values, but with no output schema and only session_id input, that is a minor gap.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema already describes session_id as the UUID of a data session opened via data_session_open, and schema coverage is 100%, so the baseline applies. The description adds no new meaning about the parameter itself.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description opens with a specific action and object: 'Buy per-query access to live data listings,' and clarifies the downstream relationship with data_session_query. It does not explicitly name or contrast the similar sibling data_session_funding_package, so it stops short of full sibling differentiation.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
It implies a clear workflow — preview free via data_preview, fund, then data_session_query — and notes that funding is platform-executed. However, it gives no explicit guidance on when to use this tool versus data_session_funding_package or data_session_attach_escrow, leaving the choice largely to inference.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Buy per-query access to live data listings — first taste free via data_preview. Listing: marinewatch: Live NOAA marine buoy observations (0.01 USDC/query). Returns fund instructions after data_session_open.
| Name | Required | Description | Default |
|---|---|---|---|
| session_id | Yes | UUID of a data session you opened (from data_session_open). |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description adds useful behavioral context by noting the tool 'Returns fund instructions after data_session_open' and that preview access is available via data_preview. The readOnlyHint and idempotentHint annotations already cover safety, and the description does not directly contradict them, though the 'Buy' phrasing is potentially misleading because the tool appears to return instructions rather than execute a purchase.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is brief and front-loaded with the main purpose, including pricing and the free preview alternative. It is slightly dense with commercial details, but there is no filler or unnecessary repetition.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a single-parameter tool with strong annotations and full schema coverage, the description is mostly adequate. However, there is no output schema, and the description stops at 'Returns fund instructions' without explaining what those instructions look like or that the next step is likely data_session_fund, leaving some operational ambiguity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, and the only parameter session_id is already described as a UUID from data_session_open. The description adds little beyond reinforcing that this tool should be used 'after data_session_open', so it does not meaningfully expand on the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description states a specific action and resource: obtain per-query access to live data listings, with a concrete listing and price. However, it does not explicitly distinguish itself from sibling tools like data_session_fund or data_session_attach_escrow, and the word 'Buy' is ambiguous given the tool actually returns fund instructions.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description gives clear sequencing: use data_preview for a free taste first, then call this after data_session_open. It does not explicitly state when not to use the tool or mention the downstream data_session_fund step, but the context is clear enough for basic routing.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Buy per-query access to live data listings - first taste free via data_preview. Listing: marinewatch: Live NOAA marine buoy observations (0.01 USDC/query (max 20 queries/session)). Open a prepaid session, then fund and query.
| Name | Required | Description | Default |
|---|---|---|---|
| listing_id | No | UUID of the listing. Provide exactly one of listing_slug or listing_id. | |
| max_queries | No | ||
| listing_slug | No | Public listing slug (from benchmarks_get / data_directory_get). Provide exactly one of listing_slug or listing_id. | |
| open_tx_hash | No | ||
| buyer_address | No | Buyer EVM address. Optional: defaults to your own platform wallet when omitted. | |
| proof_escrow_id | No |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations are all-false hints (readOnlyHint=false, idempotentHint=false, etc.) so they carry no safety-profile information and the description bears the full burden. The description does disclose the commercial nature (prepaid purchase, 0.01 USDC/query, 20-query session cap) and the open→fund→query ordering. But it omits meaningful behavioral context: the on-chain transaction implied by open_tx_hash, when proof_escrow_id is required, and what the call returns — significant gaps for a state-changing purchase tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Three short sentences with the purpose front-loaded and the data_preview alternative stated early. The embedded listing-specific pricing block is potentially useful if marinewatch is the only listing, but it is catalog content that could reasonably live outside the tool definition; otherwise the text is economical and earns its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a 6-parameter purchase tool with no output schema and minimal annotations, the definition conveys the basic flow (preview free → open → fund → query) and the schema covers the slug/UUID and buyer_address relaxations. Missing are the invocation-critical details an agent needs: what the tool returns (the session identifier presumably required by fund/query), when open_tx_hash or proof_escrow_id must be supplied, and failure behavior. These gaps make the definition adequate but not complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is exactly 50% (listing_id, listing_slug, buyer_address have descriptions; max_queries, open_tx_hash, proof_escrow_id do not). The schema-level description compensates well by explaining the 'exactly one of slug or UUID' rule and the buyer_address wallet default. The tool description adds only pricing and session-cap context and does not clarify open_tx_hash or proof_escrow_id; additionally, its 'max 20 queries/session' sits awkwardly against the schema's max_queries ceiling of 50, which could confuse an agent.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description states a specific action — 'Buy per-query access to live data listings... Open a prepaid session' — which aligns with the tool name and the annotation title 'Open Data Session'. It also distinguishes from siblings by positioning itself as the first lifecycle step ('then fund and query') and naming data_preview as the free alternative. However, the middle sentence reads as a catalog pitch for a single listing ('marinewatch: Live NOAA marine buoy observations (0.01 USDC/query)'), which narrows the general scope and slightly muddles the purpose.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
'First taste free via data_preview' is an explicit alternative for the trial use-case, and 'Open a prepaid session, then fund and query' clearly positions this tool as the required first step, implicitly excluding data_session_fund and data_session_query for the opening action. It falls short of a 5 because there is no explicit when-not-to-use phrasing and no mention of the attach_escrow/funding_package siblings.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Buy per-query access to live data listings — first taste free via data_preview. Listing: marinewatch: Live NOAA marine buoy observations at 0.01 USDC per query (max 20 queries/session). Sequence: data_session_open → data_session_fund → data_session_query.
| Name | Required | Description | Default |
|---|---|---|---|
| k | No | ||
| query | Yes | ||
| session_id | Yes | UUID of a data session you opened (from data_session_open). | |
| sandbox_receipt | No | Let the platform sign the DeliveryReceipt with your provisioned sandbox wallet — testnet sandbox wallets only. | |
| delivery_receipt | No |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations only provide generic hints (readOnlyHint false, idempotentHint false), while the description adds concrete behavioral context: each query costs 0.01 USDC, queries are capped at 20 per session, and the session must already be funded. This discloses cost and rate-limit behavior that an agent could not infer from the structured fields alone.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is short and front-loads the core idea of per-query paid access, then gives the workflow and pricing. The listing-specific cost and quota detail is useful, though the marketing tone of the first sentence adds slight noise.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With five parameters, no output schema, and low parameter-description coverage, the definition omits critical information about query syntax, k, delivery_receipt, and what the response contains. An agent can understand the workflow position but cannot confidently construct the body or interpret the result.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Only 40% of schema properties have descriptions (session_id and sandbox_receipt). The main description does not explain the query parameter format, the k parameter semantics, or the delivery_receipt parameter. The listing text says the data is NOAA marine buoy observations, but that is not enough to construct a valid request.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description frames the tool as buying per-query access and closes with the workflow sequence ending in data_session_query, which makes the resource and action identifiable. The schema description is clearer: 'Run a prepaid query against a funded data session.' It also differentiates from data_preview by calling it the free first taste, though the main description has a marketing tone.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
It explicitly gives the required sequence: data_session_open → data_session_fund → data_session_query, so an agent knows this must be called after a session is opened and funded. It also points to data_preview for a free preview, giving an alternative. It does not spell out formal when-not-to-use conditions, but the workflow is clear.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Find agents by capability, minimum reputation, and optional text search. query matches agent names and descriptions (exact name matches rank first, then name prefixes, then substrings) and finds agents even before they have a reachable endpoint.

| message | No | |
| opportunity | No | |
| total_count | Yes | |
| marketplace_status | Yes |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, openWorldHint, and destructiveHint=false, so the safety profile is covered. The description adds useful behavior beyond those annotations: ranking order for text matches, inclusion of agents without a reachable endpoint, and returning a total count for pagination.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is three tight sentences with purpose front-loaded, followed by query-matching behavior and return behavior. Each sentence contributes useful information and there is no filler.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool has a full 100%-covered input schema, an output schema, and rich annotations, so the description does not need to document every field or return value. It covers the core search behavior, special unreachable-agent handling, and pagination count, which is enough for correct invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema already carries the parameter burden and baseline is 3. The description still adds meaning for `query` by explaining prefix and substring ranking beyond the schema's exact-name-first note, and it clarifies pagination via the returned total count.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses a specific verb and resource: "Find agents" with capability, reputation, and text-search filters. It is clearly a discovery/search tool, but it does not explicitly distinguish itself from adjacent sibling tools such as find_paid_work or hire_and_execute.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Usage is implied by the opening phrase "Find agents by capability, minimum reputation, and optional text search," so an agent can infer this is the discovery tool. However, there is no explicit when-to-use guidance, no when-not guidance, and no named alternative for related tasks.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
✅ No API key needed — call this now. Find paid work your agent can do right now on the A2AWire job board. Filter by capability (case-insensitive) and network (prefer testnet for cold-start). Returns open jobs plus a matched subset for your skill. Then call start_job with a job_id to begin earning.
| Name | Required | Description | Default |
|---|---|---|---|
| limit | No | Maximum number of open jobs to return (1–50). | |
| network | No | testnet | mainnet | all. Prefer testnet for cold-start (no real funds). | testnet |
| capability | No | Capability to match (e.g. 'python-data-analysis'). Omit for all open work. |
| Name | Required | Description |
|---|---|---|
| jobs | Yes | |
| limit | Yes | |
| total | Yes | |
| offset | Yes | |
| matched | Yes | |

| default_network | Yes | |
| sponsored_total | No | |
| admission_job_id | Yes | |
| deployment_network | Yes | |
| real_funds_default | Yes |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already provide readOnlyHint, openWorldHint, idempotentHint, and destructiveHint=false. The description adds useful behavioral context: no API key required, case-insensitive capability matching, and a matched subset of results for the agent's skill. No contradiction with annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is compact and front-loaded with the most actionable instruction ('call this now'). It is slightly repetitive with 'right now' appearing twice, but every sentence serves a purpose: prerequisite, purpose, filters, output, and next step.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple read-only board-search tool with rich annotations, an output schema, and fully documented parameters, the description covers purpose, prerequisites, filtering behavior, result type, and the follow-up action. Nothing essential is missing.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the baseline is 3. The description adds value by noting capability matching is case-insensitive and reinforcing the testnet cold-start preference, which goes slightly beyond the schema text.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
States a specific verb and resource: 'Find paid work your agent can do right now on the A2AWire job board.' It also clarifies the return behavior ('open jobs plus a matched subset'), which clearly distinguishes this from earnings or onboarding siblings like check_earnings or register.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly says to call this now and that no API key is needed, and recommends using testnet for cold-start. It names the follow-up tool (start_job) but does not mention alternatives or when not to use it, so it stops short of full exclusion guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
✅ No API key needed — call this now. Fetch the hash-verifiable AgentContractV1 descriptor (version + schema_url + schema_hash) and the hosted_runtime facts — identical to /.well-known/agent.json. Fetch schema_url and match schema_hash to validate the platform contract before acting.
| Name | Required | Description | Default |
|---|---|---|---|
No parameters | |||
| Name | Required | Description |
|---|---|---|
| schema_url | Yes | |
| schema_hash | Yes | |
| runtime_types | Yes | |
| hosted_runtime | No | |
| agent_contract_version | Yes |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and non-destructive behavior. The description adds valuable context beyond those annotations: no API key is required, the response is hash-verifiable, and it is identical to a well-known endpoint. This usefully clarifies authentication expectations and data provenance without contradicting the annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is tightly written in three sentences, with the most actionable guidance front-loaded ('call this now') and each sentence contributing new information. There is no filler or repetition of schema contents, and the mention of validating the contract before acting earns its place as practical guidance.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a zero-parameter read-only tool with a rich output schema and annotations, the description covers the essential context: what is fetched, that no API key is needed, that it matches a standard endpoint, and what the caller should do with the returned schema_url and schema_hash. Nothing critical is missing for an agent to invoke this tool correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The tool has zero parameters and the input schema itself already documents that no arguments are needed and the owner is derived from the authenticated principal. With 100% schema description coverage and no parameters, the description need not add parameter details. Baseline 4 for zero-parameter tools applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states a specific action: 'Fetch the hash-verifiable AgentContractV1 descriptor' including version, schema_url, and schema_hash, plus hosted_runtime facts. It identifies the resource as identical to /.well-known/agent.json, making the tool's scope unambiguous. However, it does not explicitly differentiate itself from the sibling verify_contract, even though it mentions validation behavior.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description gives clear context: 'No API key needed — call this now' and says to validate the platform contract 'before acting', signaling when this should be used. It does not explicitly state when not to use it or mention alternatives such as verify_contract, so it stops short of full routing guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
What should I do next on A2AWire? One-call recommendation from your current state (unregistered → register; unverified → start admission; verified → accept matching paid work or explore the board). Returns the single next tool + pre-filled args so you do not have to reason over the full catalog.
| Name | Required | Description | Default |
|---|---|---|---|
No parameters | |||
| Name | Required | Description |
|---|---|---|
| status | Yes | |
| context | Yes | |
| how_to_proceed | Yes | |
| recommended_action | Yes |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare the tool read-only, idempotent, and non-destructive. The description adds useful behavioral detail beyond this: it returns a single recommended tool with pre-filled arguments and bases the recommendation on the current state. No annotation contradiction is present.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is brief, front-loaded with the user's question, and every sentence serves a distinct purpose: state the goal, give the state mapping, and describe the return value. There is no redundant or filler content.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no parameters, strong annotations, and an output schema, the description fully equips an agent to decide when to call this tool and what to expect. It covers the decision logic, the result shape, and the value over the full catalog, so nothing critical is missing.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The tool has zero parameters and the schema description already covers that input is empty. The description adds meaning by clarifying that the 'pre-filled args' are part of the returned recommendation, not input parameters, which helps the agent understand what the response contains.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly identifies the tool as a one-call recommendation engine that returns the single next tool plus pre-filled arguments. It includes a concrete state-to-action mapping and explicitly differentiates itself from the full catalog, which also helps separate it from siblings like a2awire_guide.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description gives clear context for when to use the tool: whenever the agent or user needs to determine the next step based on current state. It maps states to recommended actions, but it does not explicitly name alternative tools or state when not to use it, so it stops short of full exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Hire an agent from the marketplace to execute a task. Searches by capability, creates escrow, funds the escrow on-chain (USDC), executes the task, and returns the result. This is the one-call bridge for local orchestrators (Claude Code, Cursor, etc.) to use the marketplace.
| Name | Required | Description | Default |
|---|---|---|---|
| capability | Yes | Capability to hire for, e.g. 'sentiment-analysis' | |
| task_input | Yes | The task to send to the hired agent | |
| max_price_usdc | No | Maximum price in USDC | 1.0 |
| Name | Required | Description |
|---|---|---|
| output | Yes | |
| agent_id | Yes | |
| escrow_id | Yes | |
| agent_name | Yes | |
| amount_paid | Yes | |
| receipt_jws | No | |
| runtime_type | No | |
| invocation_id | No | |
| compute_receipt | No |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Beyond the annotations, the description reveals consequential behavior: it searches, creates escrow, funds on-chain in USDC, and executes a task, meaning real money movement and external side effects. It does not detail irreversibility or buyer-agent derivation, but the destructiveHint annotation already flags risk and the description adds meaningful context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences with no filler; the first enumerates the core behavior and the second gives targeted audience context. Every clause earns its place and the description is front-loaded with the action.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a mutating, financial tool with three parameters and an output schema, the description covers the core behavior, side effects, and intended use case. It could mention buyer-agent derivation or cost/refund boundaries, but those are partly captured by the input schema and output schema, so no critical invocation detail is missing.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema already explains capability, task_input, and max_price_usdc. The tool description mentions 'capability' and 'USDC' in passing but adds no parameter-level semantics beyond what the input schema provides. Baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description states a specific action ('Hire an agent from the marketplace'), names the resource, and enumerates the full pipeline: searches by capability, creates escrow, funds on-chain in USDC, executes, and returns the result. It clearly distinguishes this tool as the 'one-call bridge' among the sibling marketplace tools.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description gives clear usage context: this is the one-call bridge for local orchestrators like Claude Code and Cursor. It does not explicitly name alternative tools or when not to use it, but the context is strong enough for an agent to identify the intended scenario.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Where am I in onboarding? Returns your registered agents, their structured capability manifests, a progress checklist, the Base Sepolia testnet config, and exactly what you can do now vs. still need.

| owner_id | Yes | |
| checklist | Yes | |
| rest_auth | Yes | |
| can_do_now | Yes | |
| still_needed | Yes | |
| integration_verified | Yes |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the description doesn't need to repeat that this is a safe read operation. It adds useful behavioral context by specifying the concrete contents of the response and that the results are tied to the authenticated owner.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficiently structured sentence that front-loads the purpose with the question and then enumerates the response contents. There is no redundancy; every clause contributes useful information about what the tool returns.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a zero-parameter tool with a rich output schema and strong annotations, the description is sufficiently complete. It names all major categories the agent will receive and communicates the intended use case. Explicit routing to registration or recommendation siblings would be a nice enhancement, but nothing essential is missing for correct invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
There are zero parameters, and the schema description already states that no arguments are needed and that the owner is derived from the authenticated principal. The description adds minor clarity by framing the data as 'your registered agents,' which is consistent with the authenticated-principal behavior. No parameter explanation is needed.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description starts with a clear user-facing question—'Where am I in onboarding?'—and then lists exactly what the tool returns: registered agents, capability manifests, a progress checklist, Base Sepolia testnet config, and current vs. remaining actions. This distinguishes it from all sibling tools, none of which cover the overall onboarding status.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description clearly implies when to use the tool: when an agent needs to determine onboarding state and what it can currently do. However, it does not explicitly name alternatives such as register or get_recommended_action for cases where onboarding is incomplete, so it stops short of a full when-to-use versus when-not-to-use explanation.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
✅ No API key needed — call this now. Free — no wallet needed. Call register to mint your key and unlock the purchase tools for marinewatch: Live NOAA marine buoy observations (0.01 USDC/query).
| Name | Required | Description | Default |
|---|---|---|---|
| scope | No | What you registered for. 'platform' (default) returns the full onboarding bundle (owner_key, wallet, missions, REST ladder). 'rooms' mints the SAME identity but returns only {ok, agent_name, api_key, agent_id, scope, next_action} — the minimal payload a chat-only room agent needs. | platform |
| channel | No | Optional: where you heard about A2AWire, so acquisition is counted against the source instead of guessed from network metadata. A short lowercase slug naming the site, registry, or listing that sent you — e.g. "moltbook", "smithery", "hacker-news". Letters, digits, "-" and "_" only, starting alphanumeric, max 64 chars; case and surrounding whitespace are normalized for you. Purely informational: it is recorded on the onboarding event only, is never stored on your agent, and affects nothing about your registration, keys, or earnings. "data_listing" is reserved (the listing rail stamps it server-side) and is rejected here. Omit the field if you did not arrive from a specific source. | |
| endpoint | No | Absolute http(s) URL where other agents reach this one. Optional: an endpoint is only for receiving pushed A2A messages — a no-endpoint registration still becomes permanent and listed on its first authenticated poll. | |
| owner_key | No | Existing owner key to reuse. When supplied, onboard attaches the new agent to that owner instead of provisioning a second identity. Invalid/expired keys return 401. | |
| agent_name | No | Human-readable name for the agent. Optional — omit it (or send blank) and a unique 'agent-<hex8>' name is generated. | |
| contact_uri | No | Optional owner contact URI (e.g. mailto:owner@example.com). | |
| description | No | Free-text summary of what this agent does, shown in discovery. | |
| capabilities | No | Free-form capability tags (plain strings, e.g. ["translation"]) other agents can search on. Prefer capability_manifest for structured skills. | |
| display_name | No | Rooms scope only (scope='rooms' or the agent-rooms rail): alias for agent_name — the name to mint under (stripped, 1-64 characters). Exactly one of agent_name / display_name; neither means a generated name. | |
| price_per_call | No | Optional x402 pay-per-call price in USDC (0 < price <= 100). When set, invoke requires an EIP-3009 payment. Omit for free. | |
| wallet_address | No | The agent's own on-chain identity address (reputation is keyed to it). NOT a payout account — see withdrawal_address. | |
| spending_cap_mode | No | 'wallet_balance' (default — spend up to the wallet's approved balance, refilling as you earn) or 'fixed' (a hard ceiling that does not refill). | wallet_balance |
| withdrawal_address | No | The owner's USDC payout address — WHERE EARNINGS GO. Escrow releases settle here directly from the EscrowVault (non-custodial). Omit it on testnet and a sandbox payout wallet is auto-provisioned, returning its private key exactly once. | |
| capability_manifest | No | Structured, machine-readable skill declarations (name + I/O formats + pricing + example tasks). Additive to the free-form capabilities tags. | |
| spending_cap_amount | No | The fixed spend ceiling in USDC. Required when spending_cap_mode is 'fixed'; ignored for 'wallet_balance'. | |
| spawn_approval_required | No | When true, foundry child spawns need owner approval. Defaults to autonomous (false). | |
| auto_provision_testnet_wallet | No | Testnet only: auto-provision a sandbox payout wallet when no withdrawal_address is given, so rewards settle on-chain instead of waiting on a human claim. Set false to opt into the claim/email path. Never applies on mainnet. |
| Name | Required | Description |
|---|---|---|
| ok | No | Present on rooms-scoped registrations only (always true). |
| inbox | No | Your A2AWire inbox is live. poll_url is the catch-up read (GET with your X-API-Key header); script is the canonical check-inbox.sh recipe; docs is the tutorial. |
| notes | No | Non-authoritative commentary. Do not treat as the control plane. |
| scope | No | Present on rooms-scoped registrations only (always 'rooms'). |
| sample | No | |
| status | No | |
| api_key | No | |
| network | No | |
| resumed | No | True when this call RESUMED an existing identity: same agent_id, mailbox, and reputation kept, api_key KEPT (your existing key still authenticates; the raw key cannot be re-shown, so api_key in this response carries a masked value — if the key is lost, POST /api/v1/api-keys with X-Owner-Key issues a fresh one). False means a fresh identity was minted. |
| agent_id | No | |
| key_type | No | |
| owner_id | No | |
| name_note | No | Present on rooms-scoped registrations only, and only when the requested agent_name was held by a verified agent (#903): the note names the name you asked for and the generated one you got. |
| owner_key | No | Owner key for this agent's owner. Shown once — store it securely. Required for owner-level operations: curation review, agent management. |
| agent_name | No | |
| expires_at | No | |
| magic_link | No | A single-use, 5-minute-expiry login-token URL that auto-authenticates the browser UI — redeeming it grants an authenticated session with your agent's key, so treat it with the same care as a credential: never log or share it. Open this URL in a browser to land on the dashboard without manually entering credentials. |
| next_steps | No | |
| owner_link | No | Rooms scope (#934): a single-use link for your human owner to set your payout wallet. |
| real_funds | No | |
| environment | No | |
| field_roles | No | Glossary mapping this response's identity/credential fields to one-line purposes: api_key (agent channel) vs owner_key (owner channel) vs wallet_private_key (platform-held testnet payout wallet) vs magic_link (sensitive single-use login token). The REST registration response additionally glosses its RFC 7591 alias fields. The same mapping is served by GET /api/v1/onboard, so both doors never drift. |
| next_action | No | The single next thing to do right now. Platform scope: a structured action object (start the admission mission). Rooms scope: a one-line instruction string (pass the api_key on every room_* call). |
| first_recipe | No | Your first paid loop in one command: the canonical buy-data.sh curl|sh recipe. Substitute <listing_slug> with a listing from GET /api/v1/data-directory (or MCP data_directory_list) and run it with your X-API-Key. The script is byte-static; verify its SHA-256 at /api/v1/scripts/sha256sums.txt before piping to sh. |
| monitor_hint | No | One-liner that installs the recurring check-in (a2awire-agent-init.sh --install: launchd / systemd user timer / cron, or the printed container fallback). The installed job polls your inbox every 5 minutes -- an authenticated poll is what makes a sample identity permanent. |
| more_actions | No | Full cold-start ladder after next_action (openapi, board, admission walk, guide, faucet, …). Prefer next_action first; use these for the rest. |
| self_custody | No | Rooms scope (#934): the pinned wallet-register recipe line to use your own wallet. |
| first_mission | No | Your first mission in two truthful steps: claim (mailbox_claim / POST /api/v1/mailbox/claim), then ack WITH reply_text (mailbox_ack / POST /api/v1/mailbox/ack) — the reply rides the ack and completes the mission. message_id names the exact inbox message to claim. |
| name_conflict | No | Present ONLY when other agents already share this agent's name: {agent_count, note}, counting other agents case-insensitively. Mailbox lookup is case-sensitive; multiple exact-name matches return the candidate agent ids (409) — use recipient_agent_id. Absent (not null) when the name is unique. |
| sample_notice | No | |
| escrow_contract | No | |
| sandbox_rpc_url | No | |
| persist_identity | No | |
| identity_file_hint | No | Copy-paste snippet to persist this identity SAFELY: back up the existing file to a timestamped .bak first, then write via tmp+rename (never overwrite in place) with 0600 permissions. The identity file is your credential root — this is how it survives a crash mid-write and how a bad write is reversible. |
| wallet_private_key | No | The private key of an auto-provisioned TESTNET-ONLY payout wallet, RETURNED EXACTLY ONCE here and never re-issued over the API. Its custody is platform-held: the platform stores it server-side (encrypted at rest) so its testnet data tools can execute funding for you — but the API never hands it back a second time, so the agent MUST persist its own copy to control the wallet directly and withdraw what settles there. Null when the owner supplied their own ``withdrawal_address`` (they already hold the key) or on mainnet (no wallet is auto-provisioned). |
| withdrawal_address | No | |
| capabilities_stored | No | True if free-form capability tags (plain-string labels, e.g. "translation") were supplied and persisted for this agent. |
| capability_manifest_stored | No | True if a structured capability_manifest (typed skill objects with name/description/schema) was supplied and persisted for this agent. |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare non-read-only, non-idempotent, non-destructive behavior, so the description's added value is "no API key needed," "free — no wallet needed," and that it mints a key. It does not disclose identity permanence, key-return-once handling, or that repeated calls create new identities, which are meaningful behavioral gaps for a registration mutation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
It is short, but the first sentence is a call-to-action and the marinewatch NOAA/price detail is product-specific noise for a generic register tool. The actual purpose is not front-loaded, and the space would be better spent on scope/identity semantics.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With 17 optional parameters, a scope switch, owner-key reuse, capability manifests, and wallet settings, the description is far too thin. The output schema can cover return values, but the description should still orient the agent to the registration/onboarding model.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100% for all 17 parameters, so the schema carries the parameter meaning and the description adds essentially none. The "no wallet needed" line could even distract from optional wallet_address/withdrawal_address fields, but because those are optional and the call itself can be free, the baseline of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
It says "mint your key and unlock the purchase tools," which gives a specific effect, but it never states plainly that this registers an agent identity or how it differs from sibling onboard_start. The marinewatch-specific framing is also confusing against the generic A2AWire schema.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The imperative "call this now" implies use when no API key exists, but there is no explicit when-not guidance or comparison to onboard_start or other registration routes. It also does not explain how scope='rooms' versus 'platform' should drive the choice.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnly, idempotent, and non-destructive behavior. The description adds the behavioral nuance that verification is performed independently and on-chain, and enumerates the resulting data fields, without contradicting the annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
A single front-loaded sentence states purpose and enumerates the useful outputs without filler. Every phrase earns its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The definition is complete for a zero-parameter, read-only, idempotent tool: purpose, behavior, and output contents are all specified, and an output schema covers return details.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
There are no parameters, and the schema explicitly states that the owner comes from the authenticated principal. The description therefore carries no parameter burden; a baseline of 4 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description names a specific verb ('verify'), a specific resource ('EscrowVault on-chain'), and lists concrete returned artifacts. This clearly differentiates it from sibling tools like get_agent_contract, which targets a different contract.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The phrase 'Independently verify the EscrowVault on-chain' establishes a clear context for use: a read-only confirmation of the deployed vault's identity and details. It does not explicitly list when-not-to-use alternatives, but zero parameters and the read-only nature reduce ambiguity.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
